Collapsible container cap



FIG. 1 is an elevational view of a telescoping container cap showing my new design in a retracted condition;

FIG. 2 is a top view thereof; and,

FIG. 3 is an elevational view thereof, showing in an extended condition.

The broken lines in the drawing depict environment only and form no part of the claimed design. 

I claim the ornamental design for a collapsible container cap, as shown and described.
